Definitions

  • the drill pipe has to be removed from the drill hole and the drill pipe is then detached from the plug-in stub, the plug-in stub removed from the boring machine and another plug-in stub, for setting and turning of the anchor, introduced into the boring machine.
  • the rotation of the anchor in the borehole is not only necessary for easier insertion of the anchor into the borehole, but it is also intended to mix z.
  • B. a two-component resin and better filling of the adhesive in the borehole can be achieved. Such a two-component adhesive hardens within a few seconds, so that immediately after tightening the anchor z. B. is possible via its anchor nut, a rotation in the opposite direction is required for insertion.
  • the stub viewed in the direction of drilling, has an essentially radial recess in front of the mating surfaces and the thread, which opens into a blind hole-like flushing channel, set-up times which are caused by the leakage of seals which are arranged in the boring machine, can be prevented by feeding the flushing medium outside the boring machine.
  • this has an external hexagon 36 with mating surfaces 37, a cylindrical threaded piece 38 being provided on these in the drilling direction.
  • the mating surfaces 37 of the stub cooperate with mating surfaces 39 of the intermediate piece 27.
  • the intermediate piece 27 further has a cylindrical recess 40 into which the threaded piece 38 can be inserted.
  • the receptacle for the rock anchor 32 and the associated nut 34 is designed analogously to that in FIG. 3.
